AGRIcuLTURAnf'MAc Innr I To all whom it may concernu Be it known'that I,ANTAn BoRBnLY, a subject of the King of=-Hungary;, residingzat Dubois,inthecounty' of- Clearfield and State of Pennsylvanimhave inventedcertain new and useful Improvements in Agricultural Machines, ofwhich'the followingv is a specification, referencebeing had therein tothe accompanying drawing:

This invention-relatesto agricultural machines and has for its primaryobject to provide a machine of this-character including two series organgs ofground workingimplementsiarranged upon opposite sides of acentral beam, and improved means for simultaneously adjusting thetwoseries of. implements with respect to said beam.

The-invention has for a more particular object to provide longitudinallyextending bars pivotally mounted at their for-ward ends upon oppositesides of a central beam, a plurality of ground workingfimplementsadjustably mounted upon the supporting bars, toggle linkconnectionsbetween the rear ends of said supporting bars, and meansmounted upon the beam and cooperatively connected to the toggle linksfor moving the implement carrying bars inwardly or outwardly toward orfrom the central beam.

It is a further general object of my invention to improve and simplifythe construction of agricultural machines of the type referred to,whereby the same is rendered highly efficient and reliable in practicaloperation, strong and durable in its construction, and capable ofmanufacture at relatively small cost.

WVith the above and other objects in view, my invention consists in thenovel features of construction, combination and arrangement of parts tobe hereinafter more fully described, claimed and illustrated in theaccompanying drawing, in which,

Figure 1 is a plan view of my improved agricultural machine; Fig. 2 is aside elevation thereof; and Fig. 3 is a section taken on the line 33 ofFig. 1.

Referring in detail to the drawing, 1 designates the central supportingbeam of the machine, the forward end of which is supported by a groundwheel 2 mounted in a suitable yoke having a standard 3 adapted to beadjustably connected to the beam by the bolts 4. To the beam 1, adjacentto the supporting wheel 2 and rearwardly thereof, the plow or otherground working tool 5 1s se- Specification orte'ttersra'tentri.Patenteareb.3,1916.

curely fixed Whilea similar plow 6 is secured tolthebeamleadjacentitoits rear end.

' Thebeam '1, which preferably; consists of a metalbar of requisitewidth' and thickness, is: -twisted:just: rearwardlyl 'of the forwardplow '5, -asindicated at 22, toprovide a horizontally} disposed sectiontherein: To this: horizontal section of the beam, atransverse bar 8 issecurely; fixed by means of the bolts orrivets'T. Toeach end of this bar8 a ground working plow or shovel 9 is suitably attached Aopair-oflongitudinally extending bars, indicated at lO and 11, respectively, isarranged upon each side of the central beam. 1., These bars arepivotally connected at theirgforward ends to the opposite endsof' thetransverse bar 8- and have their rear endspivotally connected, as at-12, totheouter ends of a pair of togglelinks13. The other or innerendsof the corresponding links inFeach'pair are pivotallyconnected toeach--otherby" means of ai short plate 14. These plates extendlongitudinally toward each other beneath the beam 11: and one of saidplates is pivotally connected, as at 15, to the lower end of a lever 16which is fulcrumed intermediate of its ends, as at 17, upon one side ofthe beam 1. To the other or upper end of this lever, one end of aconnecting bar 18 is pivotally attached;

19 designates a manually operable lever which is fulcrumed upon the beam1, as at 20, and has its lower end connected by a pivot 21 to the otherend ofthe connecting bar 18 and theother of the plates 14. This lever 19carries the usual spring pressed dog for engagement with the teeth of arack 23 fixed upon the beam.

' Between the parallel bars 10 and 11, a pair of transversely disposedlevers 24 are pivotally mounted, as shown at 25, and said levers areconnected upon opposite sides of the respective bars 10 and 11 by meansof the link bars 26. Upon the outer ends of the transverse bars 24,ground working plows or shovels 27 are suitably mounted. A rack 28 isfixed upon the bars 10 and 11 and an arm 29 depends from each of saidracks. Upon the arm 29, the lower end of a lever 30 is pivotally mountedand this lever is also pivotally connected, as'indicated at 31, to oneof the connecting links 26 between the levers 24. The levers 30 carrysuitable dogs for locking engagement with the respective racks 28. Itwill be understood that, by the manipulation of the levers 30, the pairsof ground working plows upon opposite sides of the central beam can beangularly adjusted with respect to the line of movement of the machine.When it is desired to plow or cultivate the soil upon opposite sides ofa plant row, the lever 20 is actuated which,- through its connectionwith the oppositely extending pairs of toggle links, spreads thelongitudinal supporting bars 10 and 11 apart or draws the same togetherinto closer relation to the central beam 1. In this manner, it will beunderstood that a great range of adjustment of the ground workingimplements may be obtained so that the usefulness of the machine inpractical every-day work will be greatly enhanced. It is, of course,apparent that a greater number of the relatively adjustable gangs ofplows, indicated at 27, can be employed if desired, and while I havedisclosed in the drawing a particular mounting of these plow gangs uponopposite sides of the central beam of the machine, other constructionswhich will admit of the proper angular adjustment of the implements maybe substituted therefor.

It is also to be understood'that, while I have herein referred to thepresent preferred construction and arrangement of the several elementsemployed, the machine is susceptible of considerable modification inthese respects and I, therefore, reserve the privilege of adopting allsuch legitimate changes as may be fairly embodied within the spirit andscope of the invention as-claimed.

Having thus fully described my invention,

what I desire to claim and secure by Letters Patent is In a machine ofthe character described, the combination of a beam, a transverselydisposed bar fixed to said beam, longitudinally extending'side barspivotally mounted upon said transverse'bar at their forward ends andarranged upon opposite sides of the beam, toggle link connectionsbetween the rear ends of said bars extending under the beam, manuallyoperable means mounted upon the beam and connected to the toggle linksto move the same and force said bars toward or from the central beam,and a p1urality of ground working mounted upon each of said side barsand means for independently adjusting the implements on each of saidside bars an angularly position the same with respect to the line ofmovement of the machine.

In testimony whereof I affix my signature in the presence of twowitnesses.
